Only 41 of the breakthrough cases have been confirmed as the Delta variant, but that's largely a function of the difficulty and the time required to undertake the genome sequencing to test for the variant.
"Similar to the CDC, we are not able to sequence every positive breakthrough," Santiago-Santini said. "Whole genome sequencing is the laboratory process to analyze the entire genome of an organism. ... There are other limitations to sequencing, as well, such as a two to three week time period to process them."
They can’t even mass test and determine the difference between normal flu and covid 19.
